BOlLER-TUBE CLEANER.

SPECIFICATION forming part of Letters Patent No. I725,018, dated April14, 19033.

Application filed August 2l, 1902. Serial No. 120,539. (No model.)

To MZ whom, t r11/ty concern:

Be it known that I, EDWARD M. ADAMS, a citizen ofthe UnitedStates,residing at Akron, in the county of Summit and State of Ohio,have invented certain new and useful Improvements in Boiler-TubeCleaners,of which the following is a specification.

This invention relates to turbine-cleaners for tubes and ues of boilersfor removing all scale and incrustation by a cutting and a poundingaction, the latter operation loosening the scale and breaking it up, soas to facilitate its removal by the blast of steam or other mediumpassing through the tube or iiue.

In accordance with this invention the arm carrying the cleaner-tool isadapted to berotated and is connected with the driver by a universaljoint, so as to oscillate in all directions and permit the cleaner-toolto strikel every point of the boiler-tube Within its range.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreecting the .result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of theinvention aresusceptible of moditication, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figurel is a perspective View of a boilertube cleaner of the turbine typeembodying the invention. Fig. 2 is a central longitudinal sectionthereof. Fig. 3 is a perspective View of the arm and universal jointdetached from the driver.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

4 The invention is particularly designed for use in connection with adriver or operating means of the turbine type, although it is to beunderstood that it may be applied to cleaners rotated in any manner.

As shown in the drawings, the driver consists of a turbine or motorwheel l, which is located within a casing 2, to which the steam or othermotive medium is adapted to be supplied in the well-known manner. A curb3 is secured within the casing 2 and is provided with a plurality ofinclined ways or passages for directing steam or motive agent to thebuckets or flights of the turbine or motor wheel in a series of jets,whereby the best results are attained.

The cleaner proper is coupled to the turbine, motor-wheel, or driver l,so as to rotate therewith, a universal joint being provided in itslength to admit of the arm carrying the cleaner-tools oscillating inevery direction. The cleaner comprises, essentially, a coupling end 1l,arm 5, gimbal 6, and cleanertools 7 and 8. The coupling end 4l isadapted to be attached to the driver in any substantial Way, and the arm5 is coupled thereto by a universal joint'to admit of lateraloscillation of said arm in every direction to permit the cleaner-tools 7and 8 to come in contact with every part of the boiler-tube within theirrange. A longitudinal slot 9 is provided in the arm 5 to receive thecleanertool 8, and a second slot lO is `formed at the outer end of saidarm to receive the cleanertool 7. These slots 9 and l0 are disposed at aright angle to each other, consequently giving the cleaner-tools aright-angular disposition. This relationot` the cleaner-tools isessential in order to secure the best results in the operation of themachine, as it insures the striking of one or other of the tools againstthe side of the boiler-tube being operated upon.

The cleaner-tools 7 and S are of like construction, being disks havingtransverse notches at intervals in their periphery, so as to form, ineffect, square teeth ll. The cleaner-tools are formed from besttool-steel, highly tempered, or may be case-hardened or otherwiseconstructed so as to resist wear and prevent a too rapid wearing away ofthe cutting edges. The outer cleaner-tool 7 is smaller than the innercleaner-tool 8, this being necessary to admit of said tool operatingeffectively against the inner side of the boiler-tube. The cleaner-toolsare centrally disposed with reference to the arm 5 and are rotatablymounted upon pins extended across the respective slots 9 and lO. Byhaving the cleaner-tools rotatably mounted they are IOO adapted to turn,so as to bring new portions or teeth into position for operation.

The cleaner in operation is advanced Within the boiler-tube in theWell-known manner and is rotated by means of the driver, Which in thepresent instance is the turbine or motor Wheel l, driven byA means ofsteam, cornpressed air, or other'motive medium. As the cleaner israpidly rotated, the arm 5 oscillates and causes the cleaner-tools tostrike against the walls or inner sides of the boiler-tube, therebyloosening and detaching the scale and incrustation, the same beingcarried off by the blast escaping from the turbine or motor Wheel. Asthe arm 5 rotates and simultaneously oscillates the cleaner-tdols arebrought into contact with every part of the tube Within their range, themachine being advanced to its Work as the scale is removed.

driverand means for rotating the same, and

a universal joint connecting the said tool With said driver.

In testimony whereof I affix my signature iupresence of two Witnesses.
